An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. Unlike a fixed attenuator, which imposes a constant loss, a VOA allows the loss to be adjusted from nearly zero up to tens of decibels. This capability.

An attenuator is a device designed to reduce the intensity of electrical and electromagnetic oscillations smoothly, stepwise, or at a fixed rate.
